I’ve now been running the DWScript Sample Web Server for 8 months in a metered host (Ikoula’s 1€/month VM), so it’s time for a more formal introduction article.
It served web pages and JSON dynamically generated by DWScript, using an SQLite database for storage. It ran on a Windows 2008 R2 Standard installation, minimized so that OS+Server stayed around 256 MB RAM.
As a followup to the TIOBE & Pascal micro saga, thanks to David Champion, DWScript programming is now a (very) small part of the TIOBE TPCI stats, and Oxygene became its own language at position #163.
Here is an excerpt from the TIOBE update for July 2013

Here is a summary of DWScript changes since the last update.
Language enhancement are centered around several additions for enumeration elements and sets, as well as a standard Map() method for arrays. The JIT compiler also got more capable, and there were various improvements to the support libraries and compatibility with older (D2009) and newer (DXE3) Delphi versions.

A couple days ago, a Pascal game compiled with SmartMobileStudio was accepted on the FireFox MarketPlace as a packaged app.
It had only been tested on the FireFox OS desktop simulator, how would it hold its own on a real device?
We’re not talking of flagship phones with quad-cores like a Galaxy, a Nexus 4 or an iPhone, but mainstream, single-core, sub-$100 hardware…
For a couple months now, a JIT compiler has been available in the DWScript SVN for 32bits code. The JIT is meant to be transparent, that is, execution, debugging facilities and memory layouts are similar under JIT and interpretation, the only difference is the performance.
The JIT also uses a hybrid architecture, which was designed to allow developing the JIT incrementally, which directly derives from my only working on it a few hours at a time, every once in a while.

Here is a summary of recent changes, language highlights are initial support for sets and a new Sort() method for dynamic arrays.
Apart form Linq & LLVM libraries which were previously mentioned, Brian Frost made multiple updates to the IDE Dialog. There were numerous other minor fixes and improvements, related to stability, performance and compatibility with Delphi code.

Graphics32 is a rich, high-performance 32bits graphics library for Delphi, with extensive capability. This showcase was submitted by Christian-W Budde, who is an active contributor to the Graphics32 project.
Very experimental support for LLVM in DWScript is now in the googlecode repository, thanks to the efforts of Christian-W Budde.
This is the beginning of the opening of new realms of possibilities for DWS!
LLVM support is currently centered around jit compilation, and at the moment doesn’t extend much beyond the needs of the Mandelbrot demo (see below for what is supported right now).
Here are the main DWS news items for May 2012

Visual Basic in its various incarnations and off-springs has super-powers when it comes to OLE Automation, aka late-bound COM through IDispatch.
Where do they come from?
